PLANIGRAPH® LGRHDI

Graphite gasket sheets and gaskets with multiple smooth metal inserts.
Planigraph® LGRHDI gaskets are specific for high pressure applications. Expanded graphite is supported by multiple 0.05mm laminates in 316L grade stainless steel. LGRHDI has a compressibility of 25- 30% and an elastic recovery between 15 and 20%, with a maximum assembly stress in service of 200 N/ mm2.
The residual stress after 16 hours at 300°C is greater than 45 N/mm2.
